User Authentication
Secure authentication process for users using wallet and email verification
User Authentication
Overview
The User Authentication process ensures secure access to the platform by combining wallet-based authentication with email verification. This dual-layer approach provides both security and user-friendly access management.
Authentication Flow
Step 1: Wallet Connection
Users must connect their digital wallet (MetaMask, WalletConnect, etc.) to establish their blockchain identity.
Supported Wallets:
- MetaMask
- WalletConnect
- Coinbase Wallet
- Trust Wallet
Step 2: Email Verification
After successful wallet connection, users provide their email address for additional verification and platform communications.
Technical Process
Wallet Integration
// Example wallet connection flow
const connectWallet = async () => {
if (window.ethereum) {
const accounts = await window.ethereum.request({
method: 'eth_requestAccounts'
});
return accounts[0];
}
}Authentication States
Success Scenario
- ✅ Wallet connected successfully
- ✅ Email verified
- ✅ User proceeds to database check
Failure Scenarios
- ❌ Wallet Connection Failed: User cannot connect wallet
- Action: Retry connection or try different wallet
- ❌ Email Verification Failed: Invalid or unverified email
- Action: Re-enter email and verify
- ❌ Network Issues: Connection problems
- Action: Check internet connection and retry
